The present invention relates to an improvement in pen nibs used mainlyfor writing showcards and known as Sho-wcard Nibs.

More specifically, the present invention relates to improvements inshowcard nibs' oi the kind comprehending a container cover over theconvex portion of the pen hingedly mounted on a supporting clip which isfixed in a detachable manner by its own elasticity over the body of saidpen and resilient means which correlate both the members such as todetermine their relative position, forming a receptacle for the ink,adapted to be opened for purpose of allowing the cleaning of the pen.

The object of the present invention is to provide a writing device ofthe specified kind in which the blade spring destined to maintain thecontainer cover in its positions of working and cleaning, is constitutedby a rear portion of the container cover, comprehended within twoparallel incisions in part of the length thereof and reaching its rearend, without any waste of the starting material.

A further object of the present invention is to provide a supportingclip for the said container cover wherein the points of support androtation for the same are constituted by a central portion of the rearpart of the said supporting clip, bent upwardly for providing a point ofsupport of the end of the blade spring, and two lateral ends of saidcentral portion bent forwardly in an arrangement such as to haveco-axial orifices in which the conventional lugs are to be coupled andwhich constitute the points of rotation of the said container cover.

The invention is illustrated by way of example in the accompanyingdrawing in which:

Fig. 1 shows an elevation of the device and the nib, the device beingclosed down onto the nib, in which position it forms a cover for the inkcontainer, and shows in dotted lines the device in the raised positionin order to facilitate cleaning.

Fig. 2 is a plan view of the device.

Fig. 3 shows a perspective view of the device shown in Fig. 1.

Fig. 4 is an expanded view in the order of sequence, that is to say, thenib, the clip of the container-cover device and finally the cover deviceitself, and

Fig. 5 shows, in perspective, the hinged assem- 2 bly of thecontainer-cover device with its clip but without the nib.

The container-cover device comprises two parts, shown in the drawings bythe reference numbers I and 2. Reference numeral l is the holding clipwhich serves as a seating for the container-cover device 2 and forsecuring it to the nib. This seating has two orifices through which passthe pivotal lugs with which the container-cover device is provided.

The container-cover device comprises a tongue having in its centre anorifice and intended solely for forming with the nib 3 the cavity inwhich the ink is placed. At its rearward end it incorporates two smalllugs which act as pivotal guides by which it is hingedly mounted on thesupport-' ing clip, and a blade spring which is obtained by means of twoparallel cuts, as shown in detail in the drawing, the said blade springexercising the necessary pressure for securing the containercover device2 against the body of the nib 3, and can be raised when a slightpressure is applied in that direction, whereupon it remains in verticalposition as indicated in Fig. 3 of the drawing.

When the container-cover device 2 is in the raised position, the nib isin a suitable position for cleaning without the need for removing it.Thereupon, by applying a gentle pressure the container-cover device 2returns to its normal position forming an integral whole with the nib,capable of being used for writing and ensurin easy cleaning.

The body of the nib 3 consists of a strip of any material intended forsupporting the hinged member and for forming therewith the cavity forholding the ink.

Having now particularly described and ascertained the nature of my saidinvention, and in what manner the same is to be performed, I declarethat what I claim is:

A writing device comprising a clip and a container cover hinged thereto,an upstanding projection on the central rear portion of said supportingclip, said container cover having two parallel incisions in part of thelength thereof extended to the rear end of said container cover, oneportion of said container cover comprehended within said incisions andconstituting a blade spring which has a rear end projecting from therear end of said container cover bearing upon the upper edge of saidupstanding projection of said clip for retaining the said containercover, alternatively, in a working position and in a positionsubstantially perpendicular with respect to the former, and two lateralportions at 'both sides of said parallel incisions having at the rearends thereof conventional lugs for the pivoting of said container coverto saidclip.
